My invention relates to bosom presses and, particularly, to bosompresses of the tiu'ret-type in which a rotating frame or turret has awork receiving. bed or buck provided on bothof its 5 diametricallyopposite disposed ends remote from its pivotal point and arranged to bepresented alternately below a fixed head and then moved upwardly undersuflicient pressure against the head to complete the pressing operation.

The objects of my invention are to provide a machine in which theseveral operations; namely, rotation of the frame or turret, movement ofthe pressing beds or bucks into and out of engagement with the pressinghead, and causing a suc- 15 tion if air from within the hollow pressingbeds or bucks whose upper work receiving surface is perforated orpadded, work automatically after being operator initiated by a singleoperatoroperated means and wherein none of the operations except theperformance of proper lays of material on the pressing beds or bucks andoperation of the single operator-operated means are required to be donemanually; and to provide an eflicient and yet a relatively simplemachine such that production will be speeded up and good pressingresults will be produced.

Various other objects and advantageous features of my invention will beseen in the following description and one embodiment thereof may 3 beseen in the accompanying drawings wherein similar characters ofreferences designate corresponding parts, and wherein:

Fig. 1 is .a front elevation showing a machine constructed in accordancewith my invention; Fig. 2 is a rear elevation of the machine shown inFig. 1; Fig. 3 is a detail end view taken on the line 3-4 of Fig. 2showing the frame or turret stop mechanism in normal position; Fig. 4 isa view similar to Fig. 3 but showing the frame or turret stopmechanismin a released or operated position; Fig. 5 is a sectional view taken onthe line 5-5 of Fig. 4; Fig. 6 is a sectional view taken on the line 66of Fig. 2 showing the turret operating mechanism in unoperated position;Fig. 7 is a view similar to Fig. 6 showing the frame or turret operatingmechanism in operated position; Fig. 8 is a sectional view showing theinlet and exhaust valves for the power cylinder, and Fig. 9

is a view similar to Figs. 3 and 4 but showing both' 55 .end thereof.Midway between the end posts 2 and post 3, the base I is provided with acylinder 4 having a vertically traveling piston 5 therein whose rod 6protrudes through the upper end wall of the cylinder. A frame I ispivotally mounted on the post 3 in such manner that either 5 one of itsduplicate ends can be moved to register with the piston rod 6 and sinceboth ends of the frame I are identical, only one end of the frame needbe described.

Each end of the frame 1 is provided with a 10 vertical bore 8 in which ashaft 9 is fitted to slide vertically, the shaft 9 carrying a pressingbed or buck ID on its uppermost end that is adapted'to cooperate with astationary pressing head ll rigidly secured to the under side of abeaml2 mounted on the upper ends of the posts 2 and 3. A metal tray I3 isalso carried by the shaft 9 and is disposed below the pressing bed orbuck l0. Inthe normal position of the various parts of the apparatus,the lowermost end of the shaft 9 Just clears the upper end of the pistonrod 6.

Each end of the frame 1 is also provided with a rigid depending taperingpin 14 and a lateral extension l5 provided with a vertical bore in whicha pipe lS is rigidly secured and adapted to receive a smaller pipe .I!that leads from the interior of the pressing bed or buck l0 and slideswithin the pipe It as the pressing bed or buck I0 is moved upwardly anddownwardly. Two small drain pipes l8 connect the lower portions v of thehollow pressing bed or buck with the pipe l'l whereby the condensedvapor within the buck may be drained oil. A stuffing box I9 is providedat the upper end of the pipe I 6 to form an air tight joint so thatsuction in the pipe will cause a suction on the interior of the pressingbed or buck. The lowermost end of the pipe I 6 is connected by way of apipe 20 to the central portion of the frame I where the frame isprovided with an annular hollow space 2| surrounding o beds or bucks isprovided.

As a means for locking the frame carrying the pressing beds'or bucksagainst movement about the pivot 3 when one of the pressing beds orbucks is in registry with a stationary pressing head ll, each of theshafts 9 which carry the pressing beds or bucks I0 is substantially ofthe same diameter as a piston rod 6 whereby when the piston rod is movedupwardly by air pressure being admitted below the piston 5, it willenter the bore 8 in the frame whereby the frame I will be locked againstrotation. However, as the upper end of the piston rod 6 moves downwardlysufliciently to be below the frame I, the frame is free tobe turnedabout the post 3 as a pivot so far as this particular locking means isconcerned. It will be understood that the pressing beds or bucks ID aremoved upwardly and pressed tightly against the stationary head IIalternately when compressed air is admitted below the piston 5 and whenair is released or permitted to exhaust into the atmosphere, thepressing beds or bucks I0 and the piston 5 will move downwardly to theirnormal positions by force of gravity.

In accordance with my invention, I provide an automatic operatingmechanism for rotating the frame I about the post 3 one-half revolutionor 180 at a time as soon as the piston 5 reaches its lowermostunoperated position to release the lock on the frame. Such automaticoperating mechanism consists of a bell crank lever 26, as shown in Figs.1, 2, 6 and 7,.loosely mounted on a shaft 21 that has its ends securedin suitable lugs 28 secured rigidly to the top of the base I. One arm ofthis bell crank lever 26 is arranged to swing in the path of a pin 29mounted on the extension I5 of the frame I and extending radiallyoutwardly therefrom. The other arm of the bell crank lever has abifurcated end with a pair of aligned pins 30 extending from the opposedsurfaces of such ends, there being sufficient space between the freeends of the pins 30 to straddle a vertically ex-, tending rod 3| rigidlysecured to the piston 5 and extending upwardly through a perforationprovided therefor in the upper end of the air cylinder 4. -A block 32provided with a perforation is arranged to slide freely on the rod 3|and is moved upwardly with the rod by means of a transversely extendingpin 33 carried by the rod and downwardly by a transversely extending pin34 also carried by the rod 3|.

The positions of the rod 3| and the shaft 21 relative to the bell cranklever 26 are such that the pins 30 will always be in contact with theblock 32, the action of the bell crank lever 26 being controlled by theposition of the block 32.

That is, when the block 32 is in its up position,

as shown in Fig. 6, the pins 30 will be in their up position, and whenthe block 32 is in its down position, as shown in Fig. 7, the pins 30will be in their down position. towards which. position they are at alltimes urged by a coiled spring 35, as shown in Fig. 2, which has one endsecured to the bell crank lever 26 and the other end secured to atensioning disk 36 loosely mounted on theshaft 21. Such coiled springpreferably extends about the shaft 21 and is placed under the desiredtension by turning the disk 36 counter-clockwise and securing it in itsdesired position by turning a screw 31 threaded into the lug 28 to haveits end extend into one of a plurality of notches 38 provided in theperiphery of the disk 36. Thus, the bell crank lever 26 may beconstantly spring pressed to move counter-clockwise about the shaft 2Ibut may be prevented from doing so by the pins 30 coming into contactwith the block 32. The tension of the spring 35 is adjusted to such adegree that the tension will be suflicient to move the frame one-halfrevolution or 180 when the bell crank 26 is released, this spring forcebeing resisted by the block 32 on the rod 3|. Therefore, to guardagainst bending of the rod 3I against which lateral force is expended, asuitable bracket 39 is rigidly mounted on the top of the cylinder 4 andprovided with a vertical guideway 40 in which the block 32 is arrangedto slide.

In operation, when one of the pressing beds or bucks is being movedupwardly into pressing engagement with the fixed pressing head II, theother pressing bed or buck is in a position away from the head 'I I, asshown in Figs. 1 and 2, and the only time that there is no pressing bedor buck in pressing engagement with the fixed head II is while onepressing bed or buck is moving downwardly away from the head II, whilethe frame I makes a one-half revolution, and while the pressing bed orbuck next brought into registry with the head II is moving upwardly intopressing engagement therewith. When a pressing bed or buck has beenmoved upwardly against the fixed head II, the operating parts are in theposition shown in Fig. 6, and when the frame I has completed its nextone-half revolution, the parts are in the position shown in Fig. '7.However, in actual operation, the parts never come to a complete stop inthe position shown in Fig. 'I but are left in such position at the closeof a day's run by means of a shut-ofi lever and suitable apparatushereinafter described.

The next action of the apparatus in operation and after the parts are,in the position shown in Fig. 7, is upward movement of the piston 5under the influence of fluid pressure which will move the block 32 untilthe parts are in the positions shown in Fig. 6. One arm of the bellcrank lever 26, in moving from the position shown in Fig. 'I clockwiseto the position shown in Fig. 6 wherein it engages the pin 29, passesthe pin 29 on the frame 'I and to permit such passing the pin 29 ismounted on the free end of an arm 4| which is pivotally mounted as at 42on the frame I so that the pin 29 can swing upwardly in an arcuate pathabout the pivot 42, the arm 4| carrying the pin 29 normally retainingits proper position against a stop 43 as shown in Fig. 7 by gravity.With this construction, it will be apparent that the one arm of the bellcrank lever 26 will, in one of its positions, take against the pin 29and push the frame 'I with sufficient force to cause it to make aonehalf revolution each time the block 32 is moved downwardly by finaldownward movement of the piston 5, movement of the frame beingaccomplished by action of the spring 35.

Each time the frame 'I is moved by the spring pressed bell crank lever26 for one-half revolution as hereinbefore described, the frame 'I isstopped at exactly the end of a one-half revolution by mechanismprovided at that end of the frame l remote from the head II. This stopmeans comprises an upwardly sliding spring pressed locking block 44(Figs. '3, 4 and 5) provided with a tapering hole or opening 45 in thecenter of its upper surface with which the tapered pins I4 on the frame1 cooperate to provide a lock. The block 44 is arranged to slide freelyvertically in a bracket 46 which is rigidly secured to an extension onthe base I and the block is normally held in its uppermost position by acoiled expanding spring 41 interposed between the under side of theblock and a lug 48 integral with the bracket 46. In the constructionshown, the frame I with the depending tapering pins I4 thereon rotatesclockwise when viewed from above and the being held in a depressedposition and Fig. a

top of the block 44 is inclined downwardly from its center toward oneside so that as a pin |4 contacts with the inclined surface of theblock, the block will be carnmed downwardly against the upward pressureof the spring 41 and; as the pin passes backwardly from the center ofthe block, the block will slide on a rearwardly extending inclinedsurface to permit the block-to be lifted by the spring 41 gradually.Thus, as the frame 1 approaches the end of its one-half revolution, oneof the pins |'4 depresses the block 44 and enters the tapering hole oropening 45 thereby stopping further rotation of the frame 1 in eitherdirection. Thus, another locking means is provided to be effective priorto movement of the piston rod 6 into the bore 8.

To release the frame I for further rotation and operation of themachine, the block 44 must be moved downwardly against the resistance ofthe spring 41 and, to this end, a means is provided consisting of atreadle 49 (Figs. 1, 2 and 4) pivoted at 50 to a rearwardly extendinglug 5| integral with the bracket 46. The treadle 49 carries a laterallyextending pin 52 on which a bar 53 is pivotally mounted substantially atits center, the free ends of the bar being connected to the block 44 bymeans of links 54 extendingupwardly on either side of the spring 41.tion, when the free end. of the treadle 49 is depressed, the block 44 ismoved downwardly against thetension of the spring 41. The bar 53 or aset screw 55 attached thereto is arranged to contact 7 with the underside of the lug 46 to limit the up- ,ward movement of the block 44, theset screw being provided so that the limit of movement of the block 44can be adjusted as desired.

Operative connections are provided between the treadle 49 and an exhaustvalve in such manner that when the treadle is depressed the exhaustvalve is opened and the piston 5 with the buck l0 whichis under the headI I will move downwardly, the frame 1 not ,rotating until the piston 5is practically in its lowermost position as above described.

4 In order to relieve the operator of the necessity of holding thetreadle 49 in the down position until the piston 5 reaches its lowermostposition and the frame 1 starts to move, means are provided forautomatically locking the treadle in its lowest depressed position whichconsists of a spring pressed latch 56 pivotally mounted on the block 44as at 51 in such manner that its free upper. end can swing into or outof the path of depending lugs 58 integral with the frame 1 and which areconveniently formed on the bosses 59 to which the pins M are secured orof which the pins form a part. The latch 56 is so pivoted that its upperend will swing in a plane parallel to the plane of the post 3 and, asthe frame 1 approaches the end of its one-half revolution, the upper endof the latch .56 is cammed out by the lug 58 in a direction away fromthe post 3 and against the tension of a. spring 60 (see Fig. 5).Reversely, when the block 44 is moved downwardly by depressing thetreadle 49, the upper end of the latch 56 is moved by spring 60 in adirection toward the post 3 and under the lug 58 to retain the block 44in a depressed position (Figs. 4 and 5). positions they assume when thetreadle 49 is shows the parts in the positions which they assume whenthe treadle 49 is released but before the frame 1 has started itsone-half revolution movement,. that is, with the upper end of the Withthis construc- Fig. 4 shows the parts in thelatch 56 engaging the lug 58and thus preventing upward movement of the block 44.

A treadle 6| is provided which, when depressed, opens valves andpassages to permit compressed air to pass into the cylinder 4 forliftingthe piston 5 and causing pressing engagement between one of thepressing beds or bucks l0 and fixed pressing head II and the'treadles 49and,

6| are so interlocked that both treadles cannot be depressed at the sametime but are free to be in a raised position simultaneously. Thisinterlocking mechanism comprises a bell crank lever 62 pivotally mountedas at 63 a short distance rearwardly of a horizontal pin 64 on which thetreadle 6| is pivotally mounted. The short arm of the bell crank lever62 extends toward the pin 64 and is provided with a laterally extendingpin 65 about midway between the pivotal mounting 63 and pin 64, thelaterally extending pin 65 being disposed. in a slot provided in arearward extension 66 of the treadle 6|. The long arm of the bell cranklever 62 is provided with a laterally extending lug 61 which lies belowand in the path of the treadle 49 in such 69, the upper end of the rod10 being guided by and sliding freely through a perforation provided ina lug 1| (Figs. 1 and 2) that is secured on the base and whose upperextremity is located in the circular path of two diametrically opposedperforations provided in an annular horizontal flange 12 integral withthe frame 1. The length of the rod 19 with respect to the distancebetween the treadle 6| and flange 12 is such that the treadle 6| canonly be depressed when the upper extremity of the rod 10 registers withone of the two perforations in the flange 12. That is, the upperextremity of the rod 10 normally contacts with the lower surface of theflange 1.2 to prevent the rod from being moved upwardly and the treadle6| from being depressed, the location of the perforations being suchthat when the rod 16 registers with one of the perforations in theflange 12 the one buck I9 registers with the head II and one of thetapered pins 4 is locked in the block 44 so that the apparatus is in aposition to have one of the beds or bucks I0 forced upwardly intocontact with the head II by admitting fluid pressure into the cylinder 4below the piston 5.

Fluid pressure, in this instance, compressed air, from a source ofsupply is conveyed to the apparatus through the pipe 13 which isconnected to the intake 14 of a suitable valve mechanismas shown inFigs. 1 and 8. As shown. the intake valve 15 is open and an exhaustvalve 16 is closed so that compressed air is free to pass from theintake 14 through a port 11 into the cylinder 4 below the'piston 5. Itfollows, when the positions of the valves 15 and 16 are reversed,

during the time the piston is being forced upwardly by compressed air inthe working stroke and to permit air to enter the cylinder above thepiston when the piston moves downwardly by gravity, in which instance,the exhaust valve 16 is open.

The valves 15 and I6 are arranged to be operated in unison andoppositely. That is, when one valve is open the other is closed and viceversa. Such action is conveniently accomplished by connecting the valvestems of the valves by suitable links 88 to the opposite ends of awalking beam 8| pivoted at 82 to a bracket on the base I. One end of thewalking beam 8| is extended outwardly beyond one of the link connectionswhere it is provided with a vertical perforation through which a rod 83is adapted to slide, the lower end of the rod 83 being pivotallyconnected as at 84 to one end of a walking beam 85 pivotally mounted asat 86 to a bracket on the base I. The other end of the walking beam 85is operatively connected by a link 81 to a boss 88 integral with thetreadle 6| and extending laterally therefrom in front of the treadlepivot pin 64 in such manner that the one end of the walking beam willalways move upwardly and downwardly with the treadle 6| and the oppositeend of the beam will always assume opposite positions. Adjusting nuts 89are provided above and below the walking beam 8| on the rod 83 andsuitable coiled expanding springs 88 are interposed between the nuts 89and the walking beam 8| whereby the up and down movement of the walkingbeam 85 transmitted to the walking beam 8| will be through the springs98.-

With the above construction, the inlet valve 15 for compressed air willbe open when the treadle BI is down (Figs. 1, 2, 3, and 8) and to havethe treadle 8| automatically depressed whenever the frame I is turned toa position to have one of the two perforations in the flanges I2register with the top end of the rod I8 so that the piston 5 will beautomatically moved upwardly and one pressing bed into engagement withthe fixed pressing head, a coiled contracting spring 8| is provided toyieldingly move one end of the walking beam 85 upwardly whereby thetreadle 5| will be moved downwardly. Such spring 9| is convenientlyconnected between the end of the walking beam 85 adjacent the rod 88 anda bracket 92 secured to the base I, the bracket being adapted to belowered so that the spring 8| can be disconnected when it is desired todispense with the automatic feature, for instance, at the close of adays work. However, the same result can be accomplished by lowering thespring fastening on the bracket and to conveniently. lower the springfastening for such purpose, the upper end of the spring 8| is shownattached to the lower end of a-vertically sliding rod 93 which, by meansof its bent upper end that may take the form of a handle 94, can besecured in an up position to be supported on the top of the tubularportion of the bracket 82 or in a lower position to have its bent endrest in the lower part of a slot provided in the tubular portion of thebracket 92.

In operation of the apparatus, to start the operation of the machine,the handle 84 is set in its up position as just described which willcause operation of the piston 5 to press the aligned pressing bed orbuck l8 against the head I During this time the lay of the goods is madeon the left-hand buck as seen in Fig. 1 and then the lefthand treadle oroff-treadle is depressed by the operator which will cause the onepressing bed or buck to fall away from the head, the frame I to beturned a one-half revolution, and compressed air to be admitted to thelower end of the cylinder 4 to press that particular aligned buck upagainst the head. At this time, the

other buck is in accessible position to receive another lay of goods.Thus, the only act necessary on the part of the operator is to make theproper lay of goods and depress the left-hand treadle which is thetreadle 49. Also, as herein before stated, at the close of a day's workthe handle 94 may be set in its low position to have the pressing bed orbuck in alignment with the head dropped to its unoperated position.

Referring to the drawings and the preceding description, it will be seenthat I have provided a device embodying numerous novel and. advantageousfeatures. For instance, I have provided a device in which the severaloperations, namely, rotation of the frame or turret and movement of thepressing beds or bucks into and out of engagement with the pressinghead. work automatic after being operator initiated by a singleoperator-operated means and wherein none of the operations except theperformance of proper lays of material on the pressing beds or bucks andoperation of the single operator-operated means are required to be donemanually. Means are also provided for causing a suction of air fromwithin the hollow pressing beds or bucks whose upper work receivingsurfaces are perforated or padded. I have also provided a mechanism suchthat both of the pressing beds or bucks may be brought to a loweredposition at the end of a given length of pressing operation, forinstance, a days run, instead of leaving one of the pressing beds orbucks in engagement with the fixed pressing head.
